We are glad to present another NanoWiki compilation, following 'Balancing the promises' and 'Engines On'. This year we chose the subject of Nanoparticles Before Nanotechnology simply because we were suspicious that nanoparticles are too often, in scientific and non-scientific circles, perceived as invented, while we think they should be understood as discovered. Nanomaterials are claimed to be so new that people become scared. However, before nanotechnology, one can find nanoparticles in the... Topics: Nanotechnology, Nanoparticles, Nanomaterials, Nature
This paper presents a review of zinc oxide (ZnO) asnano material and device. ZnO has gained substantial interestin the research area of wide band gap semiconductors due toits unique electrical, optical and structural properties.Recently, ZnO as nano material generates much interestamong researchers and technologists and have been used inmany devices such as UV photodetectors, light emitting diodes,solar cells and transistors. Moreover, a brief overview on ZnOrecent advances on nanoparticles,... Topics: ZnO, Nanomaterials, Nanodevices, Nanowires, Nanorods.
This article reports how the significant it is to recognize the optimal annealing circumstances when electrospun composite fibers are heated to obtain ceramic nanofibers in proper characteristics. Polyvinylpyrrolidone (PVP) and ammonium metatungstate (AMT) nanoscaled fibers have been synthesized by electrospinning aqueous solutions of PVP and AMT. The as-spun fibers and their annealing were studied by scanning electron microscope (SEM) and Raman measurements. The 500 – 600 nm thick...
